Using laser light scattering, it was discovered that there were common emissions of about a thousand droplet particles per second throughout speech, with excessive emission charges of up to 10,000 droplet particles per second .

The authors estimate that 1 min of loud speaking generates greater than 1000 droplets containing viruses .
